The synthesis and binding investigations of first generation C3v-symmetrical hydrogen bonding urea-amide based tripodal receptors, 1–6, with various anions such as acetate, phosphate, sulfate and chloride in DMSO-d6 are presented. Analysis of the 1H NMR titrations of 1–6 showed on all occasions the selective formation of 1 : 1 stoichiometries.
本文介绍了第一代 C3v 对称氢键脲酰胺基三足鼎立受体 1-6 在 DMSO-d6 中与各种阴离子(如醋酸盐、磷酸盐、硫酸盐和氯化物)的合成和结合研究。对 1-6 的 1H NMR 滴定分析表明,在所有情况下都能选择性地形成 1 :1 的化学结构。
